in this paper, quadratic rules for obtaining approximate solution of definite integrals as well as single and double integrals using spline quasi-interpolants will be illustrated. the method is applied to a few test examples to illustrate the accuracy and the implementation of the method
مقدمه: سندرم carpal tunnel (cts) به تحت فشار قرار گرفتن عصب median در داخل تونل carpal گفته می شود. بروز سندرم double crush در شرایطی است که به شاخه های عصبی که در تشکیل عصب median دخالت دارند، در ناحیه ی گردن یا نواحی بالاتر از مچ دست فشار وارد شود و یا این شاخه ها دچار التهاب شوند. در این صورت، حساسیت عصب median که در مچ دست قرار دارد، به فشار بیشتر می شود. هدف از این مطالعه، تعیین میزان شیوع...
recent progress in nanotechnology and electrochemical methods can be applied to fine control of the size, crystal structure, and surface properties of iron oxide nanoparticles. here we appliedcathodic electrochemical deposition (ced) as an efficient and effective tactic for synthesisand double coating of surface of superparamagnetic iron oxide nanoparticles (spions). in first step, bare fe3o4 n...
abstract infiltration is one of the most important phenomena which is affected by the soil physical and hydraulic characteristics. measurement of infiltration needs the high cost and is time consuming, therefore estimation of infiltration is necessary. also, due to variability of soil moisture, it is important to determine the appropriate model for the estimating the infiltration rate. the pres...
background: hepatitis b virus (hbv) vaccination is a well-known, safe and effective way for protection against hbv infection; however, non-responders remain susceptible to infection with hbv. this is so important in patients with any kind of chronic liver disease, especially chronic hepatitis c virus (hcv) patients in whom acute hbv infection may lead to decompensation of liver disease. some of...
background and aim: the double dichotic digit test (ddt) is a simple test for assessing and screening auditory processing system. the purpose of this study was to develope a double ddt, in persian language and find its basic norm values in girls aged 7 to 11 years. methods: the persian version of double ddt is composed of 3 different 25 numerical lists. numbers in each list were recorded dichot...
Testing was conducted with anionic diphenyloxide disulfonate (DPDS) surfactants (C12 and C16 alkyl moieties) with naphthalene in aqueous systems and phenanthrene in soil systems to investigate the influence of these surfactants on biodegradation of hydrocarbons. A potential for enhancement in the degradation of naphthalene was seen in C12-DPDS amended assays at low surfactant concentrations, pr...
The pharmacology of synthetic organoselenium compounds indicates that they can be used as antioxidants, enzyme inhibitors, neuroprotectors, anti-tumor and anti-infectious agents, and immunomodulators. In this review, we focus on the effects of diphenyl diselenide (DPDS) in various biological model organisms. DPDS possesses antioxidant activity, confirmed in several in vitro and in vivo systems,...
Quantitative phase imaging (QPI) brought innovation to noninvasive observation of live cell dynamics seen as cell behavior. Unlike the Zernike phase contrast or differential interference contrast, QPI provides quantitative information about cell dry mass distribution. We used such data for objective evaluation of live cell behavioral dynamics by the advanced method of dynamic phase differences ...
Previously Al-Mg alloy was densified by hot isostatic processing and subsequently consolidated by hydrostatic extrusion. Through this process high strength and high formability nanostructured bulk Al-Mg alloy was fabricated. However, it is important to handle parametric control in powder metallurgical processing in terms of relative density, which is closely associated with its mechanical prope...
